Aggressive Link Power
Aggressive Link Power Management (ALPM) is a power-
saving technique that helps the disk save power by setting
a SATA link to the disk to a low-power setting during idle
time. Power savings come at the expense of disk latency. As
such, you should only use ALPM if you expect the system
to experience long periods of idle I/O time. ALPM is only
available on SATA controllers that use the Advanced Host
Controller Interface (AHCI).
Serial ATA Port 0/1/2/3/4/5

on the system.
Option Description

PC running.
External
SATA Called external SATA or eSATA, you can now
utilize shielded cable lengths up to 2 meters
outside the PC to transform SATA to be an
external storage. enable or disable this feature.
Staggered Spin-up
Spin-up can be employed to prevent the excessive power-
consumption of spin-up from resulting in a power shortage
in computers with multiple hard drives. Staggered spin-up
typically starts one drive at a time, either waiting for the
drive to signal it is ready or allowing a predefined period
of time to pass before starting the next drive. Select to
enable or disable this feature.
